50 x 1 u = 50 u |
(a)
Change ratio into units.
Number of $10 notes = 3 u
Number of $50 notes = 1 u
Total number of notes
= 3 u + 1 u
= 4 u
(b)
Difference in the number of notes
= 3 u - 1 u
= 2 u
(c)
Total value of $10 notes
= 3 u x 10
= 30 u
Total value of $50 notes
= 1 u x 50
= 50 u
Total value of notes
= 30 u + 50 u
= 80 u
(d)
Difference in the value of notes
= 50 u - 30 u
= 20 u
Answer(s): (a) 4; (b) 2; (c) 80; (d) 20
